For a while I've been trying to replace the default Blizzard textures in the Interface folder with 'empty' textures - textures with the same size, but simply completely transparent, so the end result appears without any visible textures at all. Then, I'd simply add a custom frame in lua with a background and boom, restyled the Blizz frames.

Thing is though, I'm not good with Photoshop and Gimp. No matter what I do, when I make the textures fully transparent, they always appear in solid green ingame. I think I'm doing something wrong with the format, but I've no clue.

The texture must be saved in 32-bit format (i.e must have a alpha channel, full RGBA). The minimum width and height is 16 and the maximum is 1024 and both must be powers of 2, they don't have to be equal. The TGA texture can be saved with or without RLE (run-length encoding).

That'd be great. Currently the way it looks it's going to take a very long time - the only tool I have to convert blp files often crashes and is horribly outdated, then GIMP is incredibly slow on my Mac as well.

If a set of fully transparent textures could be maintained, it'd benefit a lot of people, as it would make skinning default windows very easy.

Wait - why do you need to convert BLP files? WoW can use TGA files directly, no need to convert.
